A nonresponsive application can cause Unity to freeze

[Steven Pemberton]

I'm using an application that at times goes into a loop and becomes unresponsive, so that Unity greys it out until it comes back.
When that happens, normally you can still run other programs from Unity, until it comes back (or until you kill the rogue).

However, if at the moment the problem application freezes I have right clicked to get a menu from the application, or some similar operation that has caused a menu to appear, then Unity becomes nonresponsive as well. Keyboard shortcuts, and clicks all fail to produce any result.

The application in my case is Opera (11.61, but it happened on earlier versions too).

Seems more of a Compiz fault

Your system is not upto date. Please update manager, update your system, reboot and then let us know if the issue occurs still so we can continue from there

Yes, this still happens, and in fact anyone can see part of it happening by opening a drop-down menu in any program, and then trying to open the dash: you can't. If a program hangs just as a menu is open, then you just can't get to the dash until the program returns (if it ever does).
